RECORDING APPARATUS - When an inkjet printer ejects ink onto a recording medium on a go path and on a return path of a carriage, if ink cannot be ejected onto the same position on the go path and on the return path, image quality becomes poor. Test patterns with shifted ejection timing are hitherto recorded on the recording medium, and appropriate timing is input as a correction value. There is also an inkjet printer which automatically reads a test pattern, but the test pattern is recorded without consideration of a state of a head, and thus, accuracy is low. Therefore, a test pattern having a long period and a test pattern having a short period are recorded, and densities of the test patterns are read by a sensor. An extremum candidate is determined from the test pattern having a long period, and rough adjustment is made first. Then, in a region around the extremum, an extremum is determined from the test pattern having a short period. An extremum corresponding to a period to which the extrema of the two test patterns belong is set as a correction value. By determining ejection timing of the recording head using the correction value, an image in which dot deviation between the go path and the return path is inhibited can be recorded.

IMAGE FORMING APPARATUS - An image forming apparatus includes a casing having a first opening and a second opening. The first and second openings each extend between an interior of the casing and an exterior of the casing. A cover has a close position in which the cover covers the first opening and the second opening, and an open position in which cover does not cover the first opening and the second opening. A shutter has a shielding position in which the shutter covers the second opening, and a retracted position. The shutter is operably connected to the cover so as to move between the shielding position and the retracted position in response to movement of the cover. A protrusion extends from the cover, and the protrusion extends through the second opening when the cover is in the close position and the shutter is in the retracted position.

IMAGING LENS, MANUFACTURING METHOD THEREOF, AND COMPOUND LENS - In an imaging lens, one compound lens and two single lenses are arranged in a lens barrel. On the light output side of the lens barrel, a filter is arranged with a distance from lens barrel. With a further distance from the filter, an imaging element is arranged. In the compound lens, a resin lens is bonded to a base member lens, having an output surface center of the resin lens displaced by a prescribed amount relative to an output surface center of the base member lens, so that a transmission decentration amount attributed to the base member lens, not including the resin lens, and the single lenses is cancelled by a transmission decentration amount by the resin lens when taken as a whole lens system. Thus, the imaging lens capable of suppressing reduction in resolving power due to transmission decentration of the lenses is obtained.
